522kWh 240kW PV BESS EV Charging Station For Commercial Fleet Electrification Infrastructure Deployment Projects

Overview

The 522kWh 240kW PV BESS EV Charging Station For is engineered as a rapidly deployable PV BESS charging station that unites solar energy storage with high-power DC output in a single transportable platform. Built around a 522kWh LFP battery bank and a 240kW bidirectional PCS, this mobile EV charger reaches remote sites, temporary depots and event grids where fixed infrastructure is unavailable or too costly to install. Because the entire solar-storage-charging chain travels as one unit, operators avoid trenching, transformer upgrades and lengthy grid-connection permits, turning weeks of civil work into a same-day set-up. The 522kWh LFP reserve stores clean solar power so that the 240kW charging port can dispatch energy the moment vehicles arrive, keeping commercial fleet uptime high even in locations with no reliable utility feed.

Solar PV input feeds the 522kWh LFP battery through MPPT tracking, while the 240kW bidirectional PCS manages both charge and discharge with tight voltage and current control. Peak shaving trims demand charges for commercial fleet operators, and the mobile chassis allows the station to be towed or lifted between sites within hours, cutting civil works to a minimum. In off-grid mode the 522kWh reserve powers vehicles entirely from stored solar energy, while in grid-connected mode the EMS blends PV, battery and utility supply to minimise cost. Multi-level BMS protection, thermal management and an IP-rated enclosure keep the mobile EV charger operating reliably across dust, rain and wide temperature swings, so rapid deployment never comes at the expense of safety or availability.

Key Advantages

• Rapid deployment: the wheeled or skid-mounted chassis enables relocation and commissioning within hours, with no fixed civil works, trenching or transformer upgrades required before charging can begin.
• Grid-independent charging: the 522kWh LFP battery sustains extended off-grid sessions for commercial fleet vehicles at remote, temporary or weak-grid sites where a utility connection is absent or unreliable.
• Solar integration: MPPT PV input continuously replenishes stored energy, lowering diesel, fuel and grid reliance while maximising renewable self-consumption for the mobile EV charger.
• Peak shaving: the bidirectional PCS trims demand peaks and reduces utility demand charges by discharging stored solar energy during high-load and high-tariff windows.
• High-power output: 240kW DC charging with CCS2 connectors supports fast turnaround for buses, trucks, vans and mixed fleet EVs even in field conditions.
• Rugged and safe: an IP54-rated enclosure with LFP chemistry, multi-level BMS protection and thermal management ensures reliable operation across dust, moisture and wide temperature ranges.

Integrated Solar + Storage Charging

This integrated PV BESS charging station combines solar generation, lithium battery storage and DC fast charging in one system, delivering clean, resilient energy for commercial EV fleets and microgrids.

Peak Shaving and Demand Management

Intelligent energy management stores low-cost and solar power in the battery and discharges it during peak demand, reducing demand charges, easing grid load and avoiding costly infrastructure upgrades.

Off-Grid and Grid-Connected Modes

Operating both off-grid and grid-connected, the station charges electric vehicles reliably even where grid capacity is limited, making it ideal for remote depots and renewable microgrid deployments.

Safe, Rugged and Certified

Automotive-grade LFP cells, a multi-level BMS, thermal management and an IP54/IP55 weatherproof cabinet ensure safe 24/7 commercial operation, backed by global certification and remote monitoring.

Technical Specifications

Application Scenarios

• Commercial fleet depots requiring high-power charging while reducing grid demand charges through stored solar and off-peak energy, keeping vehicles ready between duty cycles.
• Off-grid and weak-grid locations where solar energy storage sustains continuous EV charging without a strong utility connection or costly grid reinforcement.
• Public and highway charging hubs needing scalable PV BESS charging station capacity that eases pressure on the local grid during busy periods.
• Microgrid and demand-management projects balancing renewable generation, battery storage and EV loads to optimise energy cost, resilience and reliability.
• Construction sites, mining camps, seasonal logistics and emergency response operations served by a rapidly deployable, relocatable mobile EV charger.

Frequently Asked Questions

What battery capacity and charging power options are available?

MIDA integrated PV BESS EV charging stations are available in 120kWh/60kW, 200kWh/120kW, 261kWh/120kW, 418kWh/180kW and 522kWh/240kW configurations. The battery capacity (kWh) buffers solar and grid energy, while the charging power (kW) determines how fast connected electric vehicles are charged.

How does the solar + storage integrated charging station work?

The system combines photovoltaic input, a lithium iron phosphate (LFP) battery pack, a bidirectional PCS and an intelligent EMS. Solar energy is stored in the battery during the day and released to charge EVs on demand, reducing grid dependence and enabling fast charging even where grid capacity is limited.

Can the BESS charging station operate off-grid or grid-connected?

Yes. Both modes are supported. In grid-connected mode it performs peak shaving and demand-charge management; in off-grid mode the solar array and battery storage power EV charging independently, making it ideal for remote fleets, microgrids and areas with weak grid infrastructure.

How does energy storage reduce charging costs and demand charges?

The battery charges when electricity is cheap or from solar, then discharges during peak charging periods. This peak-shaving and load-shifting lowers demand charges, avoids costly grid upgrades and maximizes self-consumption of renewable energy, improving the total return on investment.

Is the lithium battery safe for commercial deployment?

Yes. MIDA uses automotive-grade LFP (LiFePO4) cells with a multi-level BMS, temperature monitoring, fire suppression and IP54/IP55 weatherproof enclosures, complying with IEC/UL safety standards for reliable 24/7 commercial and fleet operation.

Where are integrated BESS EV charging stations typically used?

They are ideal for commercial fleet depots, highway service areas, microgrids, remote and off-grid sites, logistics parks and locations with constrained grid capacity, delivering fast, clean and resilient EV charging with solar self-generation and energy storage.
